A new synthesis of nitriles from N-methoxy imidoyl bromides by photolysis

Kikugawa,Fu,Sakamoto

, p. 1061 - 1069 (1993)

N-Methoxy imidoyl bromides are synthesized in one-pot from the carboxylic acids with methoxyamine and triphenylphosphine-tetrabromomethane. Photolysis of them leads to formation of the corresponding nitriles in high yield without affecting functional groups sensitive to ordinary dehydrating and halogenating reagents.
